Claritin or Loratadine is an antihistamine that is used to treat hives, watery eyes, sneezing, cold, skin rash, runny nose, itching, and other allergy symptoms. It is also taken to cure itching and skin hives in people who have chronic skin reactions. It is available in the form of regular tablets, chewable tablets, and in liquid form. Claritin works by limiting the effects of the natural chemical histamine in your body, reducing symptoms like watery eyes, itching, and sneezing.
However, Claritin should not be used to treat a severe allergic reaction like anaphylaxis. If you have been prescribed epinephrine, use it instead of Claritin to treat a severe allergic reaction.
